ROTARY PUMP.

Specification of Letters Patent No. 22,762, dated January 25, 1859.

To al? who/m rit may concern:

Be it` known that I, GEORGE VVINGATE, of the city and county of Philadelphia and State of Pennsylvania, have invented a new and Improved Rotary Pump; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.

My invention consists in a wheel, having any convenient number of chambers, with pistons operated by a cam, in combination with a system of chambers and partitions in an exterior casing, adapted to the said wheel, the whole being constructed and arranged substantially as set forth hereafter, so as to form a rotary pump, which may be applied to any of the purposes for which reciprocating pumps are used.

In order to enable others to make and use my invention, I will now proceed to describe its construction and operation.

(n reference to the accompanying drawing, which forms a part of this speeitieation, Figure l, is an exterior view of my iniproved rotary pump, Fig. Q, a sectional elevation, and Fig. 3, a transverse sectional elevation.

Similar letters refer to throughout the several views.

A is the base plate and B the exterior eas ing of the pump, to the opposite sides of which are secured the two plates C and (l. The inside of the casing bored out slightly tapering. as seen in Fig. I3, so to be adapted to the reception of the tapering bucket wheel` which will be particularly descril'ied hereafter.

Four chambers l. Q, 3 and 4, are formed in the casing, these. chambers being separated from each other by partitions a, a', a2 and a3, against which the periphery of the bucket wheel bears. The chambers 1 and 4 communicate with each other through a pipe D. and a similar pipe D forms a` communication between the chambers 2 and 3, cocks beingl connected with the pipes. so as to eut off the communication when required. The two lower chambers 3 and 4 have a branch e. to which a pipe may be coupled, and the upper chambers 1 and Q have supplementary chambers z, which have each any convenient number of branches for receiving the ends of pipes.

A central shaft F passes directly through similar parts the pump, and is arranged to turn in suitable boxes on the standards F and F', which are secured to the base A. Surrounding and fitting close to this central shaft is a` sleeve (ir, which passes through the side C of the casing, and to which is secured a Worm wheel H, into which gears a worm I on a shaft which turns in boxes attached to the base plate A.

The bucket wheel, which is secured to a flange m on the shaft E, has its periphery divided into a number of chambers fe' by partiti ons j, and each chamber is furnished with a snugly fitting piston or sliding block n, the position of which within the chamber is controlled by the cam K, which is secured to the sleeve (i. On the periphery of the cam is a T formed projection t, grasped by jaws on each piston, the outer edges of the periphery \f the cam bearing against the under side of each piston, as seen in Fig. 3. The bucket wheel is, in most respects, similar to that described in the Letters Patent for an improvement in side wheels for steamboats.` granted to me on the 22nd day of June. A. D. 1858.

It will be observed that the side (l of the casing, at the point where the shaft E passes through it. and the side C', where the sleeve G passes through it, have spaces to be filled with packing material to prevent leaking. It will be also observed, that there is sufficient space between the opposite sides of the casing to allow the bucket wheel. when it has become worn and loose. to be set up by the stad rj, which screws into a yoke on the standard F, and bears against the end of' the shaft E.

The cam K double, so that. at every complete revolution of the bucket wheel around the cam, each piston will have made two complete reciprocating movements within its chamber.

The partitions e. of the casing are sutiiciently wide to cover one of the recesses if of the bucket wheel, and to lap over the partition on each side to a slight extent, as seen in Fig. 2. Y

Supposing the double cam K to have been moved by the worm I and worin wheel H to the position shown in Fig. in which it is. for the time being, stationary; and supposing the bucket wheel to be turning in the direction of the arrow.
